kandi X-RAY | cymem Summary

cymem is a Python library typically used in Testing, Performance Testing applications. cymem has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can install using 'pip install cymem' or download it from GitHub, PyPI.

The most useful is cymem.Pool, which acts as a thin wrapper around the calloc function:. The Pool object saves the memory addresses internally, and frees them when the object is garbage collected. Typically you'll attach the Pool to some cdef'd class. This is particularly handy for deeply nested structs, which have complicated initialization functions. Just pass the Pool object into the initializer, and you don't have to worry about freeing your struct at all — all of the calls to Pool.alloc will be automatically freed when the Pool expires.

            A weird requirements.txt format
            Asked 2021-Oct-17 at 09:29

            I downloaded a requirements.txt file from a GitHub repository, but it appears to be little different than the normal format of requirements.txt file.

            1. Can you tell me how the author generated this kind of requirements.txt file? Which tools did they use?
            2. How can I use this particular file format to instantiate the Python environment? I have tried executing the commands conda install --file requirements.txt and pip install -r requirements.txt on a Windows ‘ machine, but to no avail.

            Why am I facing PermissionError while installing SpaCy en_core_web_sm on SSH server
            Asked 2021-Aug-26 at 05:02

            I am working on a project and have shifted my environment from local windows to a linux server (via SSH). I only have limited access as the host server is from my college, I've installed many packages without issues (both with and without virtualenv). I'm working on Python 3.6.9.

            I was able to install spacy and import it but I need to use the en_core_web_sm package which has to be installed additionally using the command python3 -m spacy download en_core_web_sm. However, I consistently face a PermissionError as seen in the logs below.

            Why am I facing this error? Is it because I don't have administrator access on the /usr level (refer to last line of logs)? If yes, how come only this package in particular requires a higher level access? If no, are there any workaround for me to install the package, or do I need to contact the server administrator?

            It seems all other packages are installed under your user /home/jiayi/.local/python3.6/lib and this one tries to install itself globally in /usr/local/lib/python3.6/, not sure why. I guess you can give it installation folder or something. Look here Where does spacy language model download?

            Can't find SpaCy model when packaging with PyInstaller
            Asked 2021-May-01 at 17:26

            I am using PyInstaller package a python script into an .exe. This script is using spacy to load up the following model: en_core_web_sm. I have already run python -m spacy download en_core_web_sm to download the model locally. The issue is when PyInstaller tries to package up my script it can't find the model. I get the following error: Can't find model 'en_core_web_sm'. It doesn't seem to be a Python package or a valid path to a data directory. I thought maybe this meant that I needed to run the download command in my python script in order to make sure it has the model, but if I have my script download the model it just says the requirements are already satisfied. I also have a hook file that handles bringing in hidden imports and is supposed to bring in the model as well:

            Answered 2021-Mar-08 at 00:59

            When you use PyInstaller to collect data files into the bundle as you are doing here, the files are actually compiled into the resulting exe itself. This is transparently handled for Python code by PyInstaller when import statements are evaluated.

            However, for data files you must handle this yourself. For instance, spacy is likely looking for the model in the current working directory. It won’t find your model because it is compiled into the .exe instead and therefore isn’t present in the current working directory.

            You will need to use this API:

            https://pyinstaller.readthedocs.io/en/stable/spec-files.html#using-data-files-from-a-module

            This allows you to read a data file from the exe that PyInstaller creates. You can then write it to the current working directory and then spacy should be able to find it.

            This is something I also noticed with the BigSur updates. Although there is an active issue for this on GitHub, a work around for the time being is to run the following command before you attempt to lock your Pipfile or install any packages. Note: this will only be effective in the terminal you run this command in.

            AllenNLP fails on "to be" sentences. Something Broke along the Way
            Asked 2020-Dec-12 at 03:21

            Simple sentences involving the verb, "is" return no results for semantic role labeling, either via the demo page or by using AllenNLP in Python3.8 with the latest November Bert base model.

            For example, "I am here." returns nothing.

            In short:

            • Instances of simple "A is B" sentences don't return any results.
            • I believe there should be some sort of output, as other SRL engines do return results.
            • The same goes for "I am." The expected result is an ARG1 for "I" and a predicate of "am."
